First Angle Orthographic Projection

After viewing the video clip, please comment on the followings.1. How are the 2D drawings created in first angle orthographic projection?2. Discuss about the layout of first angle orthographic projection drawing.( Do discuss about the alignment and distance of the drawings.)

1. It is done by just using 3 2D Drawings. They are then drawn according to the drawing one want to create. 2. These 3 2D Drawings would be align accordingly to the shape of the object. They would be placed further apart from the object.

1) The 2D drawings are created in first angle orthographic projection by looking at the top, front and side view of the 3D drawing.2) In the 3D drawing, where there is a cut there, in the first angle orthographic projection, a line is used to represent that.

First angle orthographic makes use of the side view of each of the 4 sides. Example, in a square, Side A is a square, so the image of one of the side of the squares is taken. If it is a triangle, the image of one of the sides is taken
